[QUOTE="waveslayer, post: 1721913, member: 46202"] So I live at sea level and I always have to re-zero my rifles when I go hunting. Especially at altitude my 6.5 Creedmoor at 8,000' will shoot low by .4 mils. It will depend on your load you are shooting. So what I do is the following: I input into my ballistics calculator an average temp and the average altitude that I will be hunting at. I see what the 100 yard zero will be according to my app. SO, if it says I need to adjust .4 mils, I re-zero it to .4 mils and verify it if I can. I have done this several times and I have been dead on each time. If I didn't re-zero I would have been shooting low or high, depending on what gun I am using and load data. Get a good ballistics app like Applied Ballistics, Hornady 4DOF, and TRASOL. [/QUOTE]
